Pricing & Connection Disclosure: Prices shown above are sample illustrative estimates and not actual live pricing. AltFTool and SkyDeal do not sell or issue flight tickets directly. When you submit an alert request, we connect you directly with certified airlines, accredited online travel agencies (OTAs), and licensed booking partners who provide the actual live fares and reservation fulfillment.
06Mistake fare alerts
Occasionally, unusually low fares can appear due to pricing or filing errors. These fares can disappear or be corrected quickly.

07Less in the spotlight
Some fare opportunities are simply marketed less prominently — a regional promotion here, an off-peak window there. Without an alert they are easy to miss.
Regional or short-run promotions that never reach a homepage.
Off-peak windows on routes that rarely get the headline.
Quiet fare changes that are easy to miss without an alert.
Alerts describe fare opportunities as they are found. Availability and fare rules vary and can change without notice.
